Concrete composite material for bridge expansion joint transition area
The invention discloses a bridge expansion joint transition area concrete composite material, which comprises the following raw material components by weight: 60-80 parts of ordinary Portland cement, 30-40 parts of acrylic acid modified emulsified asphalt, 20-30 parts of hydroxyl styrene-butadiene latex, 5-10 parts of a polymer emulsion A, 2-6 parts of methyl methacrylate, 2-6 parts of 4, 4 '-diphenyl-1, 3-pentanediol monoisobutyrate, 1-3 parts of a curing agent, and 1-3 parts of a curing agent. The coating is prepared from the following components in parts by weight: 2-6 parts of dimethyl 4, 4 '-biphenyl dicarboxylate, 5-10 parts of towel gourd fibers, 10-20 parts of redispersible latex powder, 1-3 parts of a coupling agent, 1-3 parts of a chain extender and 1-3 parts of an adhesion promoter. The concrete has the characteristics of high strength and high toughness, good crack resistance and impact resistance, high bonding strength with a pavement material and expansion joint profile steel, can simultaneously meet the requirements of later strength, elasticity and toughness, impact resistance, elastic modulus and the like on the premise of meeting excellent early strength and early hardening performance, has good matching property of new and old materials, and is suitable for large-scale production. The concrete can be used for installation and construction of the bridge expansion joint, and can also be used for rapid repair of concrete in a transition area of the bridge expansion joint.
本发明公开了一种桥梁伸缩缝过渡区混凝土复合材料，所述复合材料原料按重量份包括以下组分：普通硅酸盐水泥60‑80份、丙烯酸改性乳化沥青30‑40份、羟基丁苯胶乳20‑30份、聚合物乳液A5‑10份、甲基丙烯酸甲酯2‑6份、4,4'‑联苯二甲酸二甲酯2‑6份、丝瓜纤维5‑10份、可再分散乳胶粉10‑20份、偶联剂1‑3份、扩链剂1‑3份、附着力促进剂1‑3份；具有高强度高韧性特征，抗裂抗冲击性能好，同时与路面材料及伸缩缝型钢粘接强度高，在满足具备优异的早期强度和早期硬化性能的前提下，能够同时满足后期强度、弹韧性、抗冲击、弹性模量等诸多性能要求，同时新旧材料的匹配性好，避免短时间内易再次出现开裂、破损等二次破坏，该混凝土既可用于桥梁伸缩缝安装施工，也可用于桥梁伸缩缝过渡区混凝土快速修复。
